The invention relates to a communications method of communicating states from an activation unit to a receiver via a communications bus, wherein the state may be activation/deactivation of an activation unit, and wherein the state is communicated to the receiver via a serial data stream timed by a clock signal, said data stream transmitting data packets which comprise an identification part and a data pare wherein: ● the identification part comprises a plurality of bits which identify which activation units the data packet concerns, and ● the data part comprises a plurality of bits which individually identify the state of an activation unit. The invention also relates to a system based on the communications method and comprising an activation unit and a receiver. In addition, the invention relates to an activation unit and a receiver.
A method for adjusting adjustable articles of furniture wherein said adjusting is performed by communicating between operating units and a receiver, wherein:
An actuator system comprising an operating unit and a receiver for adjusting adjustable articles of furniture, wherein activation units on said operating unit are activated/deactivated when adjusting said furniture and are capable of communicating states to the receiver via a communications bus, and wherein the state may be activation/deactivation of the activation unit, said system additionally comprising:
An operating unit for adjusting adjustable articles of furniture where an operating unit is configured to communicate states from activation units on said operating unit to a receiver, wherein activation units on said operating unit are activated/deactivated when adjusting said furniture and wherein the state may be activation/deactivation of the activation unit, and wherein the states are communicated to the receiver via a serial data stream timed by a clock signal, said data stream transmitting data packets which comprise an identification part and a data part, said identification part comprising a plurality of bits which identify the type of operating unit the data packet concerns, said data part comprising a plurality of bits which individually identify the state of an activation unit on said operating unit, said operating unit being additionally associated with:
A receiver for use in a system comprising an operating unit for adjusting adjustable articles of furniture, wherein activation units on said operating unit are activated/deactivated when adjusting said furniture and wherein the operating unit is capable of communicating states from activation units on said operating unit to the receiver via a communications bus, wherein the state may be activation/deactivation of the activation unit, and wherein the states are communicated to the receiver via a serial data stream timed by a clock signal, said data stream transmitting data packets which comprise an identification part and a data part, said identification part comprising a plurality of bits which identify which type of operating units the data packet concerns, said data part comprising a plurality of bits which individually identify the state of an activation unit on said operating unit, said receiver being additionally associated with:
An adjustable article of furniture, said furniture comprising an actuator system comprising an operating unit and a receiver for adjusting said adjustable article of furniture, wherein activation units on said operating unit are capable of communicating states to the receiver via a communications bus, and wherein the state may be activation/deactivation of the activation unit, said system additionally comprising:
